General
Description
The TYCO Type SB Flush Deck Nozzles
are washdown nozzles for use on
United States Navy ships. They are
welded into position flush with the
deck surface. The inlet to the nozzle is
sized for welding or brazing to 1/2 inch
(DN15) pipe.
The Flush Deck Nozzles have a Ball
that normally rests in the exit orifice to
prevent debris from falling into it. When
water is flowing, the Ball is lifted up and
remains centered by the combination
of the threaded insert and the inside
edges of the three webs. The sepa-
rable Truss Head Machine Screw and
Fender Washer supplied with the Type
SB Flush Deck Nozzles are used to
temporarily cover the nozzle when the
deck is being restored.
The Type SB Replacement Parts Kit
that includes a Web with Modified
Threaded Insert, Ball, Modified Insert,
Truss Head Machine Screw, and
Fender Washer is illustrated in Figure
2. A Threaded Insert Installation Tool is
also available.
